-种小型电动微耕机的设计.

In response to the problems of large shaking, high noise, inconvenient walking, and lack of protective measures in traditional micro tillers, a small electric micro tiller was designed, with a designed width of 60 cm and a depth of more than 8 cm. Through calculation, a DC motor with a power of 2.2 kW and a voltage of 72 V was selected as the power output motor of the micro tiller. According to the operating conditions, the gearbox, transmission ratio, and gears of the micro tiller were designed, and key components were verified to meet the design requirements. According to actual work requirements, estimate and select the battery capacity, select 120 Ah lithium battery as the power supply battery, and ultimately establish a three-dimensional model of the entire machine. Electric micro tillers have more obvious advantages compared to traditional gasoline and diesel power in tea gardens and greenhouse planting. In addition to being pollution-free, they also have advantages such as low vibration and adjustable speed, which have broad market prospects. [ABSTRACT FROM AUTHOR]
